Malcolm decided to put himself to the test about his feelings toward African-Americans. He was shocked by his results.

The test told him he had a moderate preference for white people. "In other words, I was biased—slightly biased—against black people … which horrified me because my mom's Jamaican," he says. "The person in my life who [I] … love almost more than anyone else is black, and here I was taking a test, which said, frankly, I wasn't too crazy about black people."

Malcolm took the test again. He found he couldn't "cheat the test" and got the same results. "Those kinds of snap decisions that make up so much discrimination or … our thoughts and feelings, they're a product of the worlds we live in," Malcolm says. "And if you live in a world, as we do, where you … turn on the television and you see a TV show and the crack dealer's always a black guy and the judge is always a white person … those images start to matter. They start to change the way the software in your head works. And that's regardless of what race you are."
